Description:

This PR fixes incorrect diagnostic output for fhzero-averaged radiation output variables. Presently, there is a significant "sawtooth" appearance to these fields (such as dswrf_ave and ulwrf_avetoa) when we expect smoother lines with jumps only at fhzero diagnostic reset times. Here is an example of the present (OLD) result and the result from the current PR (FIX) from a 24-hour S2S regression test forecast.
